Abstract
Description
Technical Field
[0001] This utility model relates to the field of all-steel tire manufacturing technology, specifically to an I-beam wheel transfer device for all-steel tire production that is structurally reasonable, easy to operate, highly efficient in inventory, and can ensure the rapid and orderly transfer of workpieces. Background Technology
[0002] During tire manufacturing, the fully loaded H-beams of the all-steel tire carcass material belt layer need to be transferred between different processing areas. Existing transfer equipment has a significant weight when fully loaded with these H-beams, requiring operators to spend considerable time moving them to their designated storage locations. Operators cannot promptly detect any abnormalities in the production process while handling materials. When temporary problems arise on-site, operators may temporarily place materials in nearby locations, causing disorganization. Furthermore, materials not entering their storage locations in the correct order can disrupt the next process's material handling, making it difficult to transport materials according to the first-in, first-out (FIFO) principle. Due to the shape of the H-beams, their stacking is unstable, posing certain safety risks during material transfer. Summary of the Invention
[0003] This invention addresses the shortcomings and deficiencies of existing technologies by proposing an all-steel tire frame belt layer I-beam wheel circulation device that improves the efficiency of material handling and workload for operators, reduces operator downtime, ensures the accuracy of first-in-first-out material rotation, maintains neatness of items in the production equipment output area, reduces the probability of abnormal materials entering the next process, improves the effectiveness of operator working time, and enhances the safety of material transfer.
[0004] This utility model achieves its purpose through the following measures:
[0005] A rotating device for producing all-steel tires using I-beam wheels is characterized by comprising a PLC controller, at least two I-beam wheel loading baskets for supporting the I-beam wheels, at least two position detection circuits corresponding one-to-one with each of the at least two I-beam wheel loading baskets, and an RFID reading and writing mechanism located below the I-beam wheel loading baskets. The position detection circuits are disposed inside the I-beam wheel loading baskets, and the signal feedback terminals of the position detection circuits are connected to the PLC controller. The RFID reading and writing mechanism is provided with an RFID antenna and an RFID reader / writer. The RFID reader / writer is connected to the PLC controller and also to the RFID antenna. The RFID antenna is disposed below the I-beam wheel loading baskets, and RFID radio frequency tags are affixed to the I-beam wheels inside the I-beam wheel loading baskets.
[0006] The RFID reading and writing mechanism described in this utility model adopts a low-frequency RFID reading and writing mechanism to read the RFID radio frequency tags carried on the I-beams in the I-beam loading basket, thereby realizing the inventory of the I-beams. Furthermore, after selecting the low-frequency RFID reading and writing mechanism, the RFID antenna can be deployed on the ground or buried underground. The RFID antenna adopts a rectangular coil. For two or more I-beam loading baskets, since the distribution distance is far, two or more RFID antennas can be deployed sequentially under the two or more I-beam loading baskets. The coils of the two or more RFID antennas partially overlap each other to avoid missed readings. The two or more RFID antennas are respectively connected to the RFID reader. The RFID reader switches different antenna coils sequentially to complete the inventory of I-beams over long distances and at multiple workstations.
[0007] The position detection circuit of this utility model adopts a photoelectric switch, which is set at the bottom of the I-beam wheel material basket or on the side of the inlet, to detect whether an I-beam wheel is being fed in. Furthermore, an indicator light is installed on the outside of the I-beam wheel material basket. When the position detection circuit receives the I-beam wheel feeding signal, the indicator light is lit under the control of the PLC controller. There are two or more indicator lights, each corresponding to at least two I-beam wheel material baskets, and the two or more indicator lights are connected to the PLC controller.
[0008] The I-beam wheel material basket of this utility model has an inclined bottom plate and a discharge port at the end of the bottom plate. A stop bar or baffle is set at the discharge port. When the transfer AGV trolley arrives at the I-beam wheel material basket containing the I-beam wheels, the stop bar or baffle can be opened, and the inclined bottom plate can be used to transport the I-beam wheels to the AGV trolley for the next process.
[0009] The bottom plate of the I-beam wheel material basket described in this utility model is made of non-metallic plate to avoid shielding RFID signals.
[0010] In use, this invention employs two or more I-beam wheel material baskets in conjunction with a transfer AGV trolley to complete the transfer of I-beam wheels in the production process. Specifically, after the I-beam wheels are used in the production process, the operator sends them into the I-beam wheel material basket at the rear of the equipment. The position detection circuit on the I-beam wheel material basket collects the I-beam wheel input signal and sends the signal to the PLC controller. The PLC controller controls the RFID radio frequency reading and writing mechanism to read the RFID tags on the I-beam wheels in the basket through the RFID antenna located below the I-beam wheel material basket, thereby completing the inventory of the I-beam wheels. When it is confirmed that there are I-beam wheels in the current I-beam wheel material basket, the PLC controller sends out the corresponding I-beam wheel material basket number and position information. The AGV trolley identifies the I-beam wheel material basket number and position information, reaches the designated position, and completes the transfer of the I-beam wheels in the basket.
[0011] Compared with the prior art, this utility model can complete the inventory and arrival detection of a large number of I-beams to be transferred, thus providing assistance for the transfer monitoring of I-beams in multiple production processes. It has significant advantages such as reasonable structure, simple operation and accurate inventory. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] Example:
[0017] This example proposes a rolling device for producing all-steel tires, comprising a PLC controller 1, at least two I-beam wheel loading baskets 2 for carrying the I-beam wheels, at least two position detection circuits 3 corresponding one-to-one with each of the at least two I-beam wheel loading baskets 2, and an RFID reading and writing mechanism located below the I-beam wheel loading baskets 2. The position detection circuits 3 are located inside the I-beam wheel loading baskets 2, and the signal feedback terminal of the position detection circuits 3 is connected to the PLC controller 1. The RFID reading and writing mechanism includes an RFID antenna 4 and an RFID reader 5. The RFID reader 5 is connected to the PLC controller 1 and is also connected to the RFID antenna 4. The RFID antenna 4 is located below the I-beam wheel loading baskets 2, and RFID radio frequency tags are attached to the I-beam wheels inside the I-beam wheel loading baskets 2.
[0018] The RFID reading and writing mechanism described in this example uses a low-frequency RFID reading and writing mechanism to read the RFID radio frequency tags carried on the I-beams inside the I-beam loading basket, thereby realizing the inventory of the I-beams. After selecting the low-frequency RFID reading and writing mechanism, the RFID antenna 4 can be deployed on the ground or buried underground. The RFID antenna 4 adopts a rectangular coil. For two or more I-beam loading baskets, since the distribution distance is far, in this example, two or more RFID antennas 4 are deployed sequentially under two or more I-beam loading baskets 2. The coils of the two or more RFID antennas partially overlap each other to avoid missed readings. The two or more RFID antennas 4 are respectively connected to the RFID reader 5. The RFID reader 5 switches different antenna coils sequentially to work, completing the inventory of I-beams over long distances and at multiple workstations.
[0019] The position detection circuit 3 described in this example uses a photoelectric switch, which is set at the bottom of the I-beam wheel material basket 2 or on the side of the inlet, to detect whether an I-beam wheel is being fed in. Furthermore, an indicator light 6 is installed on the outside of the I-beam wheel material basket 2. When the position detection circuit 3 receives the I-beam wheel feeding signal, the indicator light 6 is lit under the control of the PLC controller 1. In this example, there are two or more indicator lights 6 that correspond one-to-one with at least two I-beam wheel material baskets 2, and the two or more indicator lights are connected to the PLC controller 1 respectively.
[0020] The I-beam wheel material basket 2 described in this example has an inclined bottom plate with a discharge port at the end of the bottom plate. A stop bar or baffle is installed at the discharge port. When the transfer AGV trolley arrives at the I-beam wheel material basket containing the I-beam wheels, the stop bar or baffle can be opened, and the inclined bottom plate can be used to transport the I-beam wheels to the AGV trolley for the next process. The bottom plate of the I-beam wheel material basket 2 is made of non-metallic plate to avoid shielding the RFID signal.
[0021] In use, two or more I-beam wheel material baskets 2 are used in conjunction with a transfer AGV trolley to complete the flow of I-beam wheels in the production process. Specifically, after the I-beam wheels are used up in the production process, the operator sends them into the I-beam wheel material basket 2 at the rear of the equipment. The position detection circuit 3 on the I-beam wheel material basket 2 collects the I-beam wheel input signal and sends the signal to the PLC controller 1. The PLC controller 1 controls the RFID radio frequency reading and writing mechanism to read the RFID tags on the I-beam wheels in the basket through the RFID antenna 4 located below the I-beam wheel material basket 2, thereby completing the inventory of the I-beam wheels. When it is confirmed that there are I-beam wheels in the current I-beam wheel material basket, the PLC controller 1 sends out the corresponding I-beam wheel material basket 2 number and position information. The AGV trolley identifies the I-beam wheel material basket 2 number and position information, and reaches the designated position to complete the transfer of the I-beam wheels in the basket.
[0022] Compared with the prior art, this utility model can complete the inventory and arrival detection of a large number of I-beams to be transferred, thus providing assistance for the transfer monitoring of I-beams in multiple production processes. It has significant advantages such as reasonable structure, simple operation and accurate inventory.
